The death of a journalist's 11-month-old son in Gaza on Wednesday has prompted a flood of poignant messages online -- and media speculation -- when pictures of Jihad Misharawi, a BBC Arabic video editor, showed him carrying the body of his dead son.

Mishrawi's son, Omar, was killed after Israeli airstrikes on the Gaza Strip fell on his Gaza home, according to the BBC.

Omar is among 16 people killed in Gaza since Wednesday afternoon, including four children, according to Al Arabiya correspondents. Fighting began when Israel's targeted killing of Hamas military chief Ahmed Jaabari on Wednesday. Since then, Palestinian fighters have fired around rockets over the border.
